Facial recognition software provides a probability that a record and a image is of the same person and that process will without exception create false positives. A anti-shoplifter system would thus have to have several safety features in order to not turn into a no-fly list.
How would that system work in a fair society government by law? Would suspects not found guilty in a court of law be there? How should false positives, that is people who the computer incorrectly predict as someone else, get a chance to clear their name (face) and get compensation when it happens? Should criminals that have served their time still be locked-out for-life and denied entry to stores that share the system?
Like vigilantes, I have a hard time seeing a way which such system can be created without massive abuse. Let assume that 1% of scanned people will be false positives, and say 5% of records will be falsely added by clerks (they are not trained to be cops or judges, and some will abuse the system to intentional hurt people they know). How many people would be hurt by this system if it was shared by the majority of stores in a large town?
